I have new gears, install kit for the 14 bolt gears and a Detroit locker for that, the Jana K4 kit is on it's way here, new bearings for front and rear, and all new brake components front and rear.

I had sent my knuckles out for machining and they're on the way back. Time to get this thing where it'll roll around.

Finally made up the transmission crossmember. The Jeep came with a body lift already on it, and had spacers for the belly pan/skid/crossmember...so it was dangling pretty low. As it sits now, the crossmember bottom is 3/4" below the frame rails. I'm using a stock 2000 Silverado
rubber bushing that I can get off the shelf at any parts store. The AA engine mounts use factory rubber pucks too.

The TC sits slightly higher. Leaves me room to build some good skids around all that, in the meantime this crossmember will let me roll on the highway. Now I'm working on the front axle mounting. This involves getting the new spring perch for the pass side on there at 18 deg, making the ubolt plates, getting said ubolts, and then once in place on the springs I'll get my measurements for the cut and turn on the C's. Then that gets done and it's time to truss it...then put it all together. Lots to do but now it's more of the less mundane crap.

A bit more plucking away at things. I had some 5/8 diameter leaf spring ubolts made. I was a bit surprised with pricing nowadays, but soon realized it's been 20+ years since I had any made so it is what it is.

The other day I got to preparing the hubs/spindles for the front. The leaf perch is on the axle, about to do the final little bit of grinding to free up the C's for the cut-n-turn.

Posting this separately just to show side by side comparison with a standard rotation D44 pinion and the newer style JK rear standard rotation D44. I'll do another one when I get the ring gear off the carrier.

I'm using the Jantz Engineering kit to do the rear JK gears in my front LP D44. The bearing journals are substantially beefier than the old style, as well as the overall shaft OD. Also worth noting is the old one is a 4.10, and the new is 5.13. Notice the teeth and head of the pinion are proportionally beefier considering the ratios.

Got the front axle housing positioned under the jeep. I have 2 degree shims stacked per side, both 8's, so that puts me at 16 deg per side...a lot lol.

This only gave me an issue with the driver side where the ubolts have to go around the cast spring perch. The inner one really was the primary culprit. I'll weld some tabs onto where the tube enters the housing to make sure that outer ubolt doesn't wanna slip off the casting since it's on the edge.

I left the weight of the front rest on the axle last night. When I made the spring plates and actually used the ubolts, and rested the weight on it all, the pinion angle looked really good BUT it was pretty dark out. I'll check it more betterer today and get the C's tacked and welded in.

Inner C's set and welded up. Got them set for 7.5 deg caster. Tomorrow morning I'll clean the housing off and hit it all with primer (truss coming, just preventing flash rust til then). Then the axle goes back under the jeep. I have 2 more degree shims on the way to straighten out the driver side spring plate.

Also, I added a little touch to it...

Spent most of the day cleaning and painting.

img_20201112_185130_306_1605239703254.jpg

And then got the axle bolted back up under the jeep. I also had painted the knuckles, got them onto the housing. Still need to do the regear.

Pulled the front axle out again, hopefully for the last time. Doing the regear now with the Jantz K4 kit to put JK44 gears into an old school D44.

Well, with the holiday season upon us it's difficult to get some time in on the Jeep, but I've done a little bit of the front regear.

Had to re-drill the 3.73 and down carrier holes to 1/2in so the bigger JK bolts will fit. These Revolution gears are dual-drilled and tapped. The Jantz kit has the 1/2in variety bolts in it.

20201223_160516_1608767655972.jpg

Got the .155 provided special shim for the pinion head. With a setup bearing all the shims will be easy if depth needs adjustment. Then got the carrier shims figured out for no preload.

20201223_165955_1608767782830.jpg

The JK ring gear is so thick that there's no way I'll be setting the crosspin when I put the spider and side gears in. So back off with the not yet torqued down ring gear to do that, then it'll be ready for the initial pattern.

Got the rear wheels and tires bolted up. Just need to finish building one front hub, put it on, and bolt the fronts on. This is bigger than I figured it would be.

I built a CNC plasma table a little while back, used that on some 16ga drops.

I used my CAD 🤣🤣

Well, these are the only studs I could locate that were matching the 14b metric M14 threads, but the shoulder is a bit too long. Made a couple of spacers from some 1/4in. It's just enough to grab all the threads plus a few more on the lug nuts.
